What utter tosh some of you write?
I'd be afraid putting my family on your flights if you really are professional pilots.
It did NOT run out of fuel.
It was NOT a freak windshear (since I landed my 777 before G-YMMM).
How can it possibly run out of fuel when procedures require you to declare a Mayday if you know you will be landing with less than Final Reserve Fuel.
They didnt. PLENTY OF THE STUFF!
To start recreating what would have been the best glide speed in dirty config is a complete waste of time. Probably somewhere around the Flap speeds as per the Vref calculations is close enough for government work.
The only thing you can do last minute if you find yourself an obstacle whilst gliding towards the theoratical max glide distance flown point is by heaving the nose up, trading energy for reduced RoD but therefore landing more short than you otherwise would have done.
You can exclude pilot error from this one (and thats ALL I am going to say about)
